Grapefruit quality depends mainly on the climate and rootstock. In our points of origin, the fruit is sweeter, juicier and less bitter as it is grown in semi-tropical summer rainfall regions. In the cooler, drier Mediterranean climates, there is a tendency for the fruit to have a thicker rind, lower sugar and high acid levels in the juice, and some bitterness.
Grapefruit varieties may be divided into two groups. The first comprises white or common grapefruit varieties of which only Marsh is of any significance. The second are the pigmented varieties that are increasingly popular with consumers. Of these varieties, San Miguel produces Ruby Red and Star Ruby.
